Advantages of corrugated pipe machine



The extruders use buffer forced feeding section, the power consumption of the main drive motors is reduced by about 30%;

The flow channel section of the extruder is optimized to ensure the production of pipe at low temperature and low pressure.



The patented closed loop direct water recycled cooling system, changing moulds no need to disassemble water tubes; 

No platform design of corrugator technology, different specifications of the moulds have same center height;  

Patented towline design of pipe corrugator reduces machine impact and improves service life of pipe corrugator. 



The optimized cooling cavity wall ensures the maximum cooling cross-sectional area, so that the cooling water has enough contact surface with the moulds, and the cooling efficiency is high.



Double blades cutting process to remove waste pipe, ensure seamless connection of pipe;

The precise trigger device of corrugated pipe cutting machine ensures continuously precision cutting;

Equipped with dual hydraulic system, symmetrical center, smooth operation.



Electric height adjustment reduces labor cost;

The stacker is equipped with weighing system;

Turn over the pipe automatically.


Die head

Short flow channel design of die head (reduced by 25%) achieves low temperature and low pressure extrusion;

Optimized design of Suba double layer die head, inner and outer wall thickness and wall deviation adjustment is very stable and convenient.
